SUNDERLAND have failed with a renewed bid for Greek winger Charis Mavrias after completing the sale of James McClean.

Republic of Ireland international McClean today finalised his switch to relegated Wigan for an undisclosed fee, thought to be around the £2million mark.

But Sunderland have wasted little time in trying to land a replacement, with Greek side Panathinaikos confirming they have rejected an offer of a season-long loan for Mavrias.

The Black Cats agreed a £2.5million fee for Mavrias last month, yet the deal fell through after a series of delays.

But after seeing their coffers boosted by the sale of McClean, Sunderland have looked to boost their options out wide with a loan move for the Greek international.

Cash-strapped Panathinaikos are only interested in a permanent deal though and Sunderland will have to reprise their cash offer if they want to land the 19-year-old.

Meanwhile, McClean has penned a three-year deal with Wigan after finding himself pushed down the Sunderland pecking order following the arrival of Italian international Emanuele Giaccherini.

After exploding onto the scene during Martin O’Neill’s first few months in charge at the Stadium of Light, McClean struggled to rediscover his form last season and Sunderland have opted to cash in on the 24-year-old.

McClean made 59 Premier League appearances during two seasons at Sunderland, with his former club Derry City taking a percentage of the transfer fee.

“I’m delighted it’s all been completed and I can say I’m a Wigan Athletic player,” said McClean.

“This is a fantastic club and after speaking with the manager, I can’t wait to meet the rest of the team, start training and hopefully make my debut very soon with the aim of helping us get back to the Premier League.”
